Hettich ROTANTA

Revolution drives a Hettich ROTANTA centrifuge from a schedule, spinning at a nominated speed for a nominated duration.

Which model

The driver identifies the instrument only as a ROTANTA, and the ROTANTA range spans benchtop, floor-standing and automated models with different rotors and different limits. The figures below are for Hettich’s automated model, the ROTANTA 460 Robotic — the one intended for integration into a robotic system. Confirm your own instrument and rotor before setting a speed, because the maximum differs by rotor even within one instrument.

At a glance — ROTANTA 460 Robotic

Plate rotor	6 plates, max 5,100 rpm, max RCF 4,362
Tube rotor	24 × 50 ml, max 4,500 rpm, max RCF 4,392
Refrigeration	Available, for samples requiring cooling
Revolution control	Spin at a given speed for a given duration

Note the relationship between the two rotors: the plate rotor spins faster (5,100 rpm versus 4,500) yet reaches a marginally lower RCF (4,362 versus 4,392), because RCF depends on radius as well as speed. If your method is specified in g rather than rpm, that difference matters — converting between the two requires the rotor’s radius, and Revolution’s operation takes rpm.

Supported methods

• Centrifuge — spin at a given rpm for a given duration

That is the whole control surface. Lid and bucket handling, where your installation automates them, are not driven through this operation.

Integration

Prerequisites

• The instrument must be reachable from the Revolution host, and the rotor fitted must match the labware the method presents.
• Confirm the maximum speed for your fitted rotor and keep methods within it. The driver takes the rpm it is given.
• Loads must be balanced as the instrument requires — a centrifuge is one of the few devices in a cell where an incorrect load is a physical hazard rather than a failed run.
